Adds a simple ACL rule to the NetScaler appliance. Simple ACL rules filter IPv4 packets on the basis of their source IP addresses and, optionally, the destination port and/or protocol. Any packet with the characteristics specified in the simple ACL rule is dropped.

Name for the simple ACL rule. Must begin with an ASCII alphabetic or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the simple ACL rule is created.

aclaction

Drop incoming IPv4 packets that match the simple ACL rule.

Possible values: DENY

td

Integer value that uniquely identifies the traffic domain in which you want to configure the entity. If you do not specify an ID, the entity becomes part of the default traffic domain, which has an ID of 0.

Minimum value: 0

Maximum value: 4094

srcIP

IP address to match against the source IP address of an incoming IPv4 packet.

destPort

Port number to match against the destination port number of an incoming IPv4 packet.

DestPort is mandatory while setting Protocol. Omitting the port number and protocol creates an all-ports and all protocols simple ACL rule, which matches any port and any protocol. In that case, you cannot create another simple ACL rule specifying a specific port and the same source IPv4 address.

Minimum value: 1

Maximum value: 65535

protocol

Protocol to match against the protocol of an incoming IPv4 packet. You must set this parameter if you have set the Destination Port parameter.

Possible values: TCP, UDP

TTL

Number of seconds, in multiples of four, after which the simple ACL rule expires. If you do not want the simple ACL rule to expire, do not specify a TTL value.

Terminates all established IPv4 connections that match any of the newly configured simple ACL rules.Note: If you plan to create more than one simple ACL rule and flush existing connections that match any of them, you can minimize the affect on performance by first creating all of the simple ACL rules and then running flush only once.

Displays settings of all the simple ACL rules or of the specified simple ACL rule. To display settings of all the simple ACL rules, run the command without any parameters. To display settings of a particular simple ACL rule, specify the name of the simple ACL rule.

Integer value that uniquely identifies the traffic domain in which you want to configure the entity. If you do not specify an ID, the entity becomes part of the default traffic domain, which has an ID of 0.
